SASH-BOWER.

Svpecilcation of Letters Patent.

Application file d November 3D, 1908. Serial No. 465,038.

To all whom 'it may concern: y Be it known that l, ANTON SCHROEDER, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Sash-Bowers, of which the following is a specification.

My invention relates to improvements in sash bowers and fasteners, its object being. to provide improved means for bowing out swinging window sash and shutters, and fastening them in either open or closed position, so that the sash may be easily manipulated and firmly held against displacement.

To this end the invention consists in the construction, combination and arrangement of par-ts hereinafter described ,and claimed.

In the accompanying drawings forming part of this specification, Figure l is a perspective view of a fragment of a window frame and swinging sash fitted with the improved sash bower, with the sash held in outswung position; Fig. 2 is a perspective View upon a larger scale of the slotted Ibracket and a fragment of the stay bar, with the bar in position to be removed; Fig. 3 is' a detail showing the slotted` bracket and staybar in locked engagement, the bracket infront elevation and the stay bar in section 0n line of Fig. 2; Fig. 4 is a side View of a fragment of a window casing and sash showi the sash closed and the stay bar fasten ,and Fig. 5 is a front View of the stay bar and slotted bracket with a fragment of the window stop, showing the stay bar fastened down.

In the drawin A represents a window freine or casingaving 'a vertical strip or stop 2, and B represents a window sash hinged to the upper part of the window frame (hin in notshown) so as toswing in a vertice. p ane'.

Upon the inner face of the window sash is an angle bracket 3, to the outwardly projected lug 4 of which is pivoted a vertically swin 'ng stay bar C. At its free end the stay ar has sliding support within the anlar slotted projection of an angle vbracket g1 secured upon the inner side of the stop 2. The slotted projection of the angle bracket comprises two laterally projecting upper and lower arms 5 and 6, having end portions extending downwardlyA and upwardly, respectively, toward each other a sullicient distance to embrace and retain the stay bar which works within the slot or passage between the arms. The bracket is formed with an outwardly extending tongue or plate 13 at the base of the arms which extends to the outer'edge ofy the stop 2 and forms a guide for the proper placing of the bracket. i

The stay bar is wider than the space between` the inturned ends of the arms, so that, once within the arms, it cannot be drawn out sidewise except where the bar is notched to reduce its width suiiciently .to

permit withdrawal. To enable it to be Withdrawn when desired the` bar is formed at a convenient place along its length with a notch 7 in lts upper edge, as illustrated in Fig. 2, the lower edge of the bar being left unnotched so that it willslide smoothly over the lower arm of the slotted bracket when the window is swung out or pulled in. In order to guard against accidental removal of the bar when the sash is shaken by wind, the notch is made with vertical sides, as shown in the drawin s, and of a width just suiiicient to permit t e upper arm to pass through it.

In order that the bar, when t-he sash is bowed out, may interlock automatically with the Slotted bracket D, itis formed at its outer end with a notch 8 in its lower edge adapted to drop over the lower arm 6 of the bracket, as illustrated in Fig. 3. To prevent the bar frombeing withdrawn sidewise from between the arms 5 and Gat-the notch 8, it is formed above the notch with a shoulder 9 so that the portion of the bar above the notch Will be wider than the space between the ends of the arms, as shown in Fi 3. At its extreme free end the bar is forme with a laterally extendin linger piece 10 which forms one side of t e terminal notch 8, thus enabling the bar to be extended its entire length.V

In practice the stay bar is brought to a position where the notch 7 registers with the ends of the guide arms, and pressed in between them. It is then free to slide Within the arms. To open the sash the bar is run out through the slot or opening formed by these arms until the'notch 8 drops over the lower guide arm 6, when the sash will be `held fast in extended position, 'as shown in Fig. 1. To close the sash the stay bar is lifted out of engagement with the lower arm and permitted to slide back' through the slotted bracket untilI the sash lod es against the window stop 2. The lug 4 og the angle bracket Il will enter and pass through the slotted bracket l) and permit the stay bar to swing donn upon its pivot into the position shown in Figs. -l and 5. In this position the. sash will be held closed and cannot be swung ont until the stay bar has been lifted. I tur ther provide positive means for fastening the stay bar in downturned position, in order that it ma)v not become-displaced when the window is shaken by the wind. F or this purpose the stay bar is formed near its free end with a slotted opening ll. which tits over a pin 12 driven into the window stop in position to enter the slotted opening, as illustrated in Figs. t and 5. As shown in dotted lines in Fig. 5, the stay bar has to be sprung in sidewisc in order that it may be litted over the piu. locked and wind or the shaking of the window.

In order to permit the sash to be drawn snugly against the outer face of the window strip 2, the slotted bracket D must be positioned upon the window strip so that the angular or lateral arms 5 and (i will stand far enough back from the outer face ot' the strip to receive `and accommodate between them and the plane of the face of the strip the base portion of the angle bracket 3 upon the sash. The adjustment of the bracket in this position is a matter of some nieety, and, if done by the eye alone, is apt to result in iinperfeetclosing of the sash or interference with the swinging of the stay bar. l have therefore provided, as a positive and accurate guide tor the adjustment ot the bracket, a blunt ended tongue 13 extending ontnardly from the base of the bracket (that is, the portion at the base of the arms) and projecting beyond the plane of the arms a distance equal to the space desired between the arms and the outer face of the window strip. Thus, when the outer end of t-he tongue, which is made parallel with the arms, is placed tluslrwith the outer tace of the window strip, the slotted bracket will stand in proper position, as shown in Fig. of the drawings.

I claim as my invention:

l. The combination, with a window frame and swinging sash, of a slotted angle bracket upon the inner side of the Frame, said bracket being formed with spaced upper and lower arms extending laterally into the windo\.\` opening, a forwardly projecting lug upon the sash,l and a stay bar pivoted to the lug so as to swing in a vertical plane, the stay bar (bien over the pin it will be firmly incapable ot dislodgment b v the y having sliding support between the arms, ot the slotted bracket and the lug being con structcd to enter and pass through the space between the arms of the bracket, so Ias to permit the stay bar to swing down upon the inside of the bracket.

2. The combination, with a window frame having a Window striprupon its inner side, ,of a slotted angle bracket secured upon the inner side of the stri with its slotted angular portion extending laterally into the window opening and having at the base of the angular portion a tongue projecting ontwardly beyond the outer face thereof, a

swinging sash, a forwardly projecting lug upon the sash, and a stay bar pivotally connected with the lug so as to swing in a vertical plane and having sliding support in the slotted bracket.

3. The combination, with a window frame having a window strip upon its inner side. of a slotted angle bracket secured upon the inner side of the strip, vsaid bracket being;l formed with spaced upper and lower arms extending laterally into the window opening and havingr at the base a tongue projectingl outwardly beyond the outer face of the arms. a swinging sash, an angle bracket secured upon the face of the sash and having a too wardly projecting lug, and a. stay bar pitiotally connected with the luv' so as to swing in a vertical plane, the stay bar having sliding support between the arms of the slotted' bracket and being formed with a removal notch and a locking notch.

4. The combination, with a window frame Y having a window strip upon its inner side.

cfa slotted angle bracket secured upon tlu` inner side of the strip, said bracket being formed with spaced upper and lower arms extending laterally into the window opening, j

and having at the base of the arms a tongue projecting outwardly beyond `the outer faces thereof, the outer face of the tongue being Hush with the outer face of the Window strip. a swinging sash, an angle bracket secured upon the face of the sash, and a stay bar pivotally connected with the angular projection. ot' said bracket and having sliding support in the slotted bracket.

In testimony whereof I affix my signature in presence. ot' two witnesses. i
